Snivy063, there are a few original TMs I can think of off the top of my head that I don't like. First, there's Fissure and Horn Drill. OHKO moves rely way too much on luck. For just that reason, they are banned by most competitive rules. Then, there's Teleport. I mean... really? The only purpose it has in battle is to run from wild battles. It does nothing in trainer battles. And then Metronome. Again, it relies on luck.
